Viewing LineType Appearance

By Madhukar Moogala

I have recieved this query, user would like to get appearance of LineTypeRecord or LineTypes through API.

We can use Comments API to gets the Linetype appearance in the form of ascii string.

Code:

public static void LineTypeAppearance()
        {
            Database database = HostApplicationServices.WorkingDatabase;
            var ed = AcCore.Application.DocumentManager.MdiActiveDocument.Editor;
            using (Transaction t = database.TransactionManager.StartTransaction())
            {
                var symTable = (SymbolTable)t.GetObject(database.LinetypeTableId,
                                                        OpenMode.ForRead);
                foreach (ObjectId id in symTable)
                {
                    var symbol = (LinetypeTableRecord)t.GetObject(id, OpenMode.ForRead);
                    ed.WriteMessage(string.Format("\nName: {0}\t Appearance: {1}",
                                                    symbol.Name, symbol.Comments));
                }

                t.Commit();
            }
        }

Output
